Image and video signals require large transmission bandwidth and storage, leading to high costs. The data must be compressed without a loss or with a small loss of quality. Thus, efficient image and video compression algorithms play a significant role in the storage and transmission of data.Image and Video Compression: Fundamentals, Techniques, and

In November 2015, Buenos Aires, Argentina became the location of several important events for geo-professionals, with the simultaneous holding of the 6th International Symposium on Deformation Characteristics of Geomaterials, the 15th Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XV PCSMGE), the 8th South American Congress on Rock Mechanics (SCRM), as well as the 22nd Argentinean Congress of Geotechnical Engineering (CAMSIGXXII). This synergy provided a unique opportunity to exchange ideas and discuss current and future practices in the areas of soil mechanics and rock mechanics, and their applications in civil, energy, environmental, and mining engineering. This book presents the proceedings of the 6th International Symposium on Deformation Characteristics of Geomaterials. As well as 118 articles selected for publication after peer review, it includes 7 lectures delivered by invited keynote speakers and the Third Bishop Lecture, delivered by Professor Herve Di Benedetto of the University of Lyon, France, who presented a reference work on the advanced testing and modeling of bituminous bounded and unbounded granular materials. The conference brought together practitioners, researchers and educators from around the world engaged in the understanding of the deformation properties of geo-materials before failure, and the small strain parameters as fundamental characteristics of geo-materials. The main topics covered by the symposium include experimental investigations from very small strains to beyond failure, including multi-physical approach; HTC M coupling behavior, characterization and modeling of various geo-materials and interfaces; and practical prediction and interpretation of ground responses: field observation and case histories.

Drawing upon a wide range of unpublished sources, including files from the recently-released Foreign and Commonwealth Office'migrated archive', Fighting EOKA is the first full account of the operations of the British security forces on Cyprus in the second half of the 1950s. It shows how between 1955 and 1959 these forces tried to defeat the Greek Cypriot paramilitary organisation, EOKA, which was fighting to bring about enosis, that is the union between Cyprus and Greece. By tracing the evolving pattern of EOKA violence and the responses of the police, the British army, the civil administration on the island, and the minority Turkish Cypriot community, David French explains why the British could contain the military threat posed by EOKA, but could not eliminate it. The result was that by the spring of 1959 a political stalemate had descended upon Cyprus, and none of the contending parties had achieved their full objectives. Greek Cypriots had to be content with independence rather than enosis. Turkish Cypriots, who had hoped to see the island partitioned on ethnic lines, were given only a share of power in the government of the new Republic, and the British, who had hoped to retain sovereignty over the whole of the island, were left in control of just two military enclaves.

Biohistory is a revolutionary new theory that explores the biological and behavioural underpinnings of social change, including the rise and fall of civilisations.Informed by significant research into the physiological basis of behaviour conducted by author Dr Jim Penman and a team of scientists at RMIT University and the Florey Institute in Melbourne, Australia, Biohistory examines how a complex interplay between culture and biology has shaped civilisations from the Roman Empire to the modern West.Penman proposes that historical changes are driven by changes in the prevailing temperament of populations, based on physiological mechanisms that adapt animal behaviour to changing food conditions.It details the history of human society by mapping the effects of these epigenetic changes on cultures, and on historical tipping points including wars and revolutions. It shows how laboratory studies can be used to explain broad social and economic changes, including the fortunes of entire civilizations. The author's shocking conclusion is that the West is in terminal and inevitable decline, and that its only hope may lie with the biological sciences. Drawing on the disciplines of history, biology, anthropology and economics, Biohistory is the first theory of society that can be tested with some rigour in the laboratory. It explains how environment, cultural values and childrearing patterns determine whether societies prosper or collapse, and how social change can be both predicted—and potentially modified—through biochemistry.

The text Modern Electrochemistry (authored by J. O'M. Bockris and A. K. N. Reddy and published by Plenum Press in 1970) was written between 1967 and 1969. The concept for it arose in 1962 in the Energy Conversion Center at the University of Pennsylvania, and it was intended to act as a base for interdisciplinary students and mature scientists~hemists, physicists, biologists, metallurgists, and engineers-who wanted to know about electrochemical energy conversion and storage. In writing the book, the stress, therefore, was placed above all on lucidity in teaching physical electrochemistry from the beginning. Although this fundamentally undergraduate text continues to find purchasers 20 years after its birth, it has long been clear that a modernized edition should be written, and the plans to do so were the origin of the present book. However, if a new Bockris and Reddy was to be prepared and include the advances of the last 20 years, with the same degree of lucidity as characterized thefirst one, the depth of the development would have to be well short of that needed by professional electrochemists.

1.1. Definition of Terms-Thrombosis, Thromboembolic Disease, Atherosclerosis, and Blood Clotting The terms heart attack or myocardial infarction are more commonly used than thrombosis. The infarct-muscle destruction is simply the end result and thrombosis is the real cause of the heart attack. Thrombosis may be defined as the process of formation of a coalescent or agglutinated solid mass of blood components in the blood stream. Thrombi formed in either arteries or veins often cause occlusion in the vascular system and prevent blood flow. Obstruc­ to the blood vessel usually occurs at the site where the thrombi deposit. tion Furthermore, thrombi may break loose, travel through the circulating blood stream, and cause obstruction at some distal point of narrowing elsewhere. The mass or thrombus that moves is referred to as an'embolus.'The two phenomena are lumped together under the term thromboembolic disease. Thrombosis that reduces blood supply to the heart is the primary factor in heart attacks.

Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) • at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con­ cerned if the printing and distribution of the volumes were handled by an interna­ tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor­ poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer­ sities do report theses submitted in previous years but not reported at the time.

Sealing of boreholes and underground excavations has not received much engineering attention until fairly recently. The growing awareness of and sensitivity to environmental concerns of the technical community as well as of the public at large has resulted in an increasing recognition of the fact that these geological penetrations may have an environmental impact. The issue of possible contamination resulting from migration along boreholes, adits, shafts or tunnels unquestionably has been raised most forcefully with­ in the context of nuclear waste disposal. Several nuclear waste disposal programs, notably the Civilian and the Defence programs of the US De­ partment of Energy, the US Nuclear Regulatory Commission and the Canadian and Swedish radioactive waste disposal programs have conducted major research efforts aimed at developing adequate seal designs for penet­ rations in host rock formations for high-level nuclear waste repositories. While a considerable data base has been gathered over the last two decades or so with regard to the performance of seals, most of the information is presented in research reports and widely scattered papers in journals and proceedings of conferences. Hence, the materials are not readily accessible to potential users such as designers, contractors or regulators who are not familiar with nuclear waste disposal programs.

The definitive guide to unsaturated soil— from the world's experts on the subject This book builds upon and substantially updates Fredlund and Rahardjo's publication, Soil Mechanics for Unsaturated Soils, the current standard in the field of unsaturated soils. It provides readers with more thorough coverage of the state of the art of unsaturated soil behavior and better reflects the manner in which practical unsaturated soil engineering problems are solved. Retaining the fundamental physics of unsaturated soil behavior presented in the earlier book, this new publication places greater emphasis on the importance of the'soil-water characteristic curve'in solving practical engineering problems, as well as the quantification of thermal and moisture boundary conditions based on the use of weather data.

Employees, organizations and society alike should grow the virtual workplace, as the multiple, tangible benefits of telework for each of these three stakeholders largely outweigh the costs. To help stakeholders benefit from the virtual workplace, the authors analyze four key issues: telework adoption, implementation, tracking and impacts. They develop the comprehensive EOS framework to examine both the interaction among employees, organizations and society, and the linkages among telework impacts, tracking, implementation and adoption.Unique features of the book include an integrative framework for increasing telework adoption; practical tips - specific to each stakeholder - on how best to implement and measure telework; and an analysis of original survey data exploring the virtual workplace adoption decision.Readership for this book includes academic experts on telecommuting, policymakers involved in transportation, human resource or environmental policies, and managers and employees considering telework.

Human and Ecological Risk Assessment: Theory and Practice assembles the expertise of more than fifty authorities from fifteen different fields, forming a comprehensive reference and textbook on risk assessment. Containing two dozen case studies of environmental or human health risk assessments, the text not only presents the theoretical underpinnings of the discipline, but also serves as a complete handbook and'how-to'guide for individuals conducting or interpreting risk assessments. In addition, more than 4,000 published papers and books in the field are cited. Editor Dennis Paustenbach has assembled chapters that present the most current methods for conducting hazard identification, dose-response and exposure assessment, and risk characterization components for risk assessments of any chemical hazard to humans or wildlife (fish, birds, and terrestrials). Topics addressed include hazards posed by: Air emissions Radiological hazards Contaminated soil and foods Agricultural hazards Occupational hazards Consumer products and water Hazardous waste sites Contaminated air and water The bringing together of so many of the world's authorities on these topics, plus the comprehensive nature of the text, promises to make Human and Ecological Risk Assessment the text against which others will be measured in the coming years.

Offers thorough coverage of the remediation of soils contaminated by hazardous wastes, including materials, analytical techniques, cleanup design and methodology, characterization of geomedia, monitoring of contaminants in the subsurface, and waste containment. Cites specific case studies in hydrocarbon remediation that offer a concise overview of possible technological approaches.

Flextime, telecommuting, compressed work week, job sharing, downshifting, and hot desking—these terms are infiltrating our vocabulary at an increasing rate, keeping pace with change in the workplace. Although there is a large body of literature on the changing nature of work and workplace flexibility, there is no handbook that synthesizes the research on all aspects of this topic. Pulling together the vast literature on this subject, Avery and Zabel explain the concept of flexible work, trace the origin and growth of this workplace trend, and review the research on a range of flexible work arrangements.Workplace flexibility is international in scope. Companies, both in the United States and abroad, have become increasingly interested in implementing flexible work arrangements. The authors include a chapter on companies in North America, Western Europe, and the United Kingdom that have been leaders in implementing flexible work arrangements. They identify areas ripe for additional research, suggest a broad array of resources, and discuss strategies for locating additional information, including relevant databases, Internet resources, organizations, and search terms. This is a valuable handbook for managers, researchers, and students working or studying in the areas of human resource management, industrial/organizational psychology, and the sociology of work.

'This is a philosophical study of qualitative consciousness, characteristic examples of which are pains, experienced colors, sounds, etc. Consciousness is analyzed as the having of qualia. Phenomenal properties or qualia are problematical because they lack appropriate bearers. The relation of having is problematical because none of the typical candidates for this relation — introspection, inner monitoring, higher level thoughts — explains why it is like something to have a quale. The qualia problem is solved by introducing a bundle theory of phenomenal objects. Phenomenal objects are bundles of qualia. Thus there is no need for independent qualia bearers. The having problem is solved by introducing a bundle theory of the self. To have a quale is for it to be in the bundle one is. Thus no further relations are needed to explain how qualia are had. This study strives for phenomenological adequacy. Thus the first-person point of view dominates throughout. (Series A)'

Engineering geology is an interdisciplinary subject concerned with the application of geological science to engineering practice, and it is therefore important for the engineering geologist to recognize the boundary between engineering application and purely scientific enquiry. Much research in applied clay science results from imperfectly understood engineering behaviour. Engineering geology is most closely allied to the geotechnical and materials areas of civil engineering. The scope of the present book is limited to the influence of clay but because clay is almost ubiquitous in earth materials the subject still remains broad. In soil and rock, clay is the smallest size fraction, but it is that very fact which often determines its major influences on engineering behaviour.In this book the author reviews the importance of clay in engineering geology and summarizes present knowledge in this field. The plan of the book has remained unchanged since the first edition was published in 1968 but the text, diagrams and reference lists have all been extensively updated. The first 5 chapters review the classification, origin, composition, fabric and physical chemistry of clays. Behavioural aspects, covered in the following 4 chapters, include moisture interaction, strength and rheology, soil stabilization and the use of clays as materials. The final 3 chapters describe methods of analysis of clays and soils.Clay in Engineering Geology contains material drawn from a wide variety of sources and, together with its literature review and indexes, will provide much of value to geologists, mineralogists, civil and geotechnical engineers concerned with applied clay science.

This book provides an in-depth discussion of various aspects of metal ecotoxicology. State-of-the-art information and techniques in areas ranging from metal behavior in surface waters to bioaccumulation kinetics and toxicokinetics to community effects are presented in a hierarchical arrangement. Specific topics discussed include metals in abiotic components of ecosystems, autecology (effects of metals relative to the individual or a single species), and metals in marine and freshwater systems in the context of synecology (species associated and interacting as a unit). This is an important book that will be useful to researchers, risk assessment consultants, regulatory personnel, and teachers and students.

The environment, as modified and created by people, is largely about the use of information, its generation and exchange. How do recent innovations in the technologies of information management and communication affect our use of space and place, and the way we perceive and think about our surroundings?This volume provides an international, exploratory forum for the complex phenomenon of new information and communication technology as it permeates and transforms our physical world, and our relation to it: the architectural definition of our surrounding, geographical space, urban form and immediate habitats. This book is a reader, an attempt at registering disciplinary changes in context, at tracing subtexts for which most mainstream disciplines have no established language. The project is to give voice to an emerging meta-discipline that has its logic across the specializations.A wide range of professionals and academics report findings, views and ideas. Together, they describe the architecture of a postmodern paradigm: how swiftly mutating the proliferating technology applications have begun to interact with the construction and reading of physical space in architecture, economics, geography, history, planning, social sciences, transport, visual art - but also in the newer domains that have joined this spectrum through the very nature of their impacts: information technology and telecommunications.The space navigated in this volume is vast, both in physical terms and in its virtual and analogous form. It ranges from the space that immediately encompasses, or is simulated to encompass, the human body - as in buildings and virtual tectonics - to that of towns and regions. We stay clear of molecular-scale space, and of dimensions that are larger than earth.

Proceedings of the 10th International Clays Conference, Adelaide, Australia, July 18 to 23, 1993. Clays have provided us with the most active ingredients in soils, with building materials, with pottery and ceramics for both utility and decoration, and with coatings and fillers for paper, among other uses. The unique properties of these apparently everyday materials are being studied and used in an increasing range of industrial and environmental applications. Clays: Controlling the Environment provides a valuable compendium of the latest results from the complete range of clay-related scientific research. It includes coverage of the economic and environmental issues as well as directions for further research and development in many vital and expanding industries. All papers in these proceedings were subject to peer review. The topics discussed are: Clays in industry and the environment Surface and interlayer reactions Clay mineral structures and chemistry Methods of investigation Clays in geology Soil mineralogy The emphasis of this book reflects the vital role that clays play in controlling natural, polluted and technological environments.

This new volume from the SETAC (Society of Environmental Toxicology and Chemistry) Special Publications Series examines the phenomenon of persistent pollutants in the seas and oceans. Unlike the highly visible and obvious effects caused by oil, certain chemicals have unseen but long-term and far-reaching effects on the marine ecosystem. They often have long half-lives, are carried great distances and pass easily through the food chain from prey to predator. The behaviour and effects of these persistent pollutants on each type of marine animal (invertebrates, vertebrates, fish, mammals and fish-eating birds) are described. A final overview draws the observations and conclusions together presenting a work that provides a foundation for understanding the behaviour of persistent pollutants in the marine environment.

Adsorption of Metals by Geomedia, serves as a needed resource for this topic which has received much attention during the past 15 years. The book provides an in-depth review of the field, followed by numerouschapters that document the current status of adsorption research for a variety of metals by geomedia ranging from individual minerals to sediments and soils. Adsorption mechanisms are detailed and precipitation is presented as a distinct sorption process.Virtually all factors affecting the extent of metal adsorption are examined, including the effects of selected anions, competition among metals, pH, metal concentration, loading, variable metal adsorption capacity, ionic strength, hydrogen exchange and stoichiometry, and solids concentration. A variety of adsorption models are briefly presented and some are used to extend laboratory studies to field sites. The book is comprised of a collection of papers contributed by leading investigators from Canada, France, the Netherlands, the United Kingdom and the US. Includes a wide-ranging review of the status of adsorption research and a prospectus on future research Details all known factors affecting the extent of adsorption Covers basic adsorption equations and interrelationships Clearly documents experimental procedures Presents adsorption data for eleven metals and three other elements Uses normalization to greatly reduce apparent variability among absorbents Provides extensive literature citations and a comprehensive index

Since the publication of the first edition ten years ago, significant developments have occurred in the use of admixtures in concrete. Eight new chapters and a full update of the preceding ten chapters bring this book up to date; reflecting the relative advances made in the science and technology of different groups of admixtures. The increased role and development of admixtures in concrete technology is evidenced by a number of conferences, publications, and novel admixtures available in the market place. These developments in the field caused the modification of many chapters in the first edition in order to reflect the advances. Although individual chapters refer to standards and specifications of admixtures, those only interested in the standards or techniques used in investigating admixtures will find the second chapter (Research Technologies, Standards, and Specifications) useful. Admixtures are not as inert as may be presumed. They may chemically interact with the constituents of concrete and affect the properties of the fresh and hardened concrete and its durability. The third chapter deals with these aspects. It was important to devote a chapter to recent attempts in developing new admixtures.
